Wusuo learned that according to the official announcement of Fusion (by IPOR), the IPOR team received an alert on January 6 and discovered a malicious transaction targeting the Fusion Optimizer Vault on Arbitrum. After investigation, the vulnerability was found to have caused a loss of 336,000 USDC. The attack targeted only a specific legacy Fusion Vault, and due to its unique configuration, only this Vault was susceptible to such attacks. The loss amount represents less than 1% of Fusion's total funds. Currently, the IPOR team is collaborating with relevant security institutions to track and recover the funds. Meanwhile, IPOR DAO will compensate for the losses through fiscal reserves, and all affected depositors will receive full compensation. Other Fusion Vaults are unaffected.
